2 Claims.

This invention relates to new and useful improvements in a dust suction device for cleaning furs, clothing, etc.

The invention has for an object the construction of a device as mentioned which is characterized by a casing substantially of inverted, saucerlike shape andhaving alongitudinal s lot in its top over Vwhich the furs, clothing and the like may be passed during the cleaning operation.

More particularly, the invention contemplates the provision of an air duct within the casing for extending over said slot and connected with a vacuum dust collector bag, and an arrangement for blowing or sucking the dust into said bag.

Still further the invention proposes the provision of a rotary brush extended across said longitudinal opening and adapted to engage against the fur and clothing moved over the opening to brush the dust therefrom.

Furthermore, the invention proposes the provision of an element or elements upon the brush adapted to strike against the metal or material at the sides of the longitudinal opening or upon other material in the vicinity thereof to assist in better shaking the dust from the furs or clothing.

A further object of this invention is the arrangement cf a porous wire mesh material eX- tended over the opening so as to prevent buttons and other small parts from the clothing engaging therein, but arranged in such a manner as not to interfere with the proper operation of the device.

Another object of the invention is the construction of a device as described which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended 'claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosurez- Fig. 1 is a plan view of a device constructed according to this invention.

Fig. 2 is a perspective view of the device shown in Fig. 1.

Fig. 3 is a bottom elevational view of Fig. 1.

Fig. 4 is a sectional view taken on the line 4 4 of Fig. 1.r

Fig. 5 is a sectional of Fig. 4.

Fig. 6 is a fragmentary horizontal sectional View taken on the line 6-6 of Fig. 4.

View taken on the line 5 5 The dust suction device for furs, clothing, etc., according to this invention, includes an inverted, saucer-like casing I0 adapted to be attached upon a table II and formed with a longitudinal slot I2 in its top. An air duct I3 is arranged within the 5 casing I0 and extends over the opening I2 and connects with a vacuum dust collector bag I 4.

A blower I5 is arranged within the casing I!) and is connected with the duct I3 so as to create suction at the slot I2, and to discharge air drawn 10 in through the slot into'the bag.

A 'combination brush and vibrator I 6 is arranged with the duct I3 immediately adjacent the slot I2 for brushing and beating the furs, clothing, etc. which are drawn or passed over the 15 top opening in the casing.

'I'he casing I0 has several curved side portions |021, I 0b, etc. and a comparatively flat top portion 10. `Screeninaterial I1 is mounted on the at portion I 0c and is adapted to cover the openremovably in position by the provision of several pegs I8 mounted thereon and engaging in receiving openings in the top portion I0c of the casing. The air duct I3 in the vicinity of the slot I2 is of suflcient compass to encase the slot. It then .decreases in compass until the discharge end 53a, which is substantially of cylindrical form. The 30 dust bag I4 is adapted to have its neck engaged on the discharge portion |32. The blower I5 is mounted in the wall of the casing and has its air discharge I5ad arranged at an angle to the side wall of the duct I3 so as to blow through the duct 35 and cause suction at the slot (I2) end of the duct. The brush I6 is driven by an electric motor 20 which is mounted upon the wall of the casing. 'Ihis electric motor is connected by a belt or chain 2| with a pulley 22 upon a shaft 23 of the brush 40 I6. The shaft 23 has another pulley 24 at its other end which is connected by a belt or chain 25 with the blower I5 so as to drive the blower during the operation of the brush. 'Ihe table II is formed with openings I Ia over which the casing I 0 extends. The duct I3 extends through this opening and connects with the bag I 4, which is located beneath the table.

The combination brush and vibrator comprises a central hub portion I6a from which bristles Ib project. 'I'hese bristles are arranged in groups spaced from each other, and between these groups there are vibration` elements. Each vibration element consists Vof a longitudinally extending metallic impact member I6c or members radially slidably supported and limited against complete displacement by headed studs I6d which are mounted upon the hub I6. Springs Iiie resiliently urge the impact members I6c into extended positions.

The outer ends of the members I6c are tapered, as clearly shown in Fig. 4, so that the sides thereof act as cam surfaces in forcing the retraction of these members when they engage resisting parts. These resisting parts consist of the material of the casing I adjacent the sides of the opening I2 on the screen member I'I.

As the combination brush and vibrator I6 operates the bristles extend through the openings in the member I1 and brush the dust from the fur, clothing, and the like. Simultaneously, the fur, clothing and like is subjected to a beating operation indirectly by the impact members IiiC causing vibration of the member I1. The dust which is freed from the fur will be drawn inwards by the suction created by the blower I5.

'I'he shaft 23 has a removable section 23a which is releasably held by couplings 23h. It is possible to disconnect the couplings 23b so as to remove the brush IE. It may then be replaced by another type of brush, or the identical brush repaired, cleaned, etc.

A speed control arm 20' of the motor 20 is projecting through slot II'Idv of the casing I0. The motor may be connected to the usual A. C. or D. C. supply by a connecting plug or the like.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the preoise construcion herein disclosed and the right is reserved to all changes and modifications coming within the Scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A dust suction device for furs, clothing, etc., comprising an inverted saucer-like casing adapted to be attached on a table and having a longitudinal slot in its top, an air duct within the casing and extending below said slot, a blower connected with said duct so as to create suction at the slot and to discharge air drawn in through the slot, and a combination brush and vibrator within the duct and adjacent said slot for brushing and beating furs, clothing, etc., passed over the top of said casing,

said casing having several curved sides and a at top to facilitate the sliding of furs, clothing, etc. thereover, and a screen member being removably mounted upon said flat top for covering said slot to prevent buttons and the like from projecting into the casing.

2. A dust suction device for furs, clothing, etc., comprising an inverted saucer-like casing adapted to be attached on a table and having a. longitudinal slot in its top, an air duct within the casing and extending below said slot, a blower connected with said duct so as to create suction at the slot and to discharge air drawn in through the slot, and a combination brush and vibrator within the duct and adjacent said slot for brushing and beating furs, clothing, etc., passed over the top of said casing, said casing having several curved sides and a flat top to facilitate the sliding of furs, clothing, etc. thereover, and a screen member being removably mounted upon said flat top for covering said slot to prevent buttons and the like from projecting into the casing, said cover material having a curved portion to accommodate the curvature of the combination brush and vibrator.
